There is two options to climb Eagle Rock, follow Eagle Springs Fire road and return back where you went. The second option creates a loop returning to Trippet Ranch via Musch Trail, which I did.
The hike starts at the sign Trippet Ranch Trailhead, and Eagle Rock is 2 miles away from there. There are two junctions at the beginning, the first one clearly mark trail, turn left, and the second one said The LATITUDE, turn left there.
There are plenty of green area along the hike, so you can easily meet deer  close to you. Continue follow Eagle Springs Fire road, and there are 4-way junction just before the rock. On the left, Musch Trail, which is the way go down when returning. Go straight, and continue the road. When you almost close to the rock, follow the Eagle Rock sign and you can get to the Eagle Rock finally. There is another summit on the right from the bench.
On way down, there is a junction with no sign, turn left. You will encounter two paved road, the first one you have to cross the road and continue the trail. On the second paved road, turn left and follow the road. There is a bridge, and you get to Musch Trail sign and parking lot.
The trail is easy to follow, and the sign is clear on the fire road. If you go down via Musch Trail, there is little confusing place. Just follow my advice, you will get through it.
